1.10 REMOTE CONTROLS AND ROOM
CHRONOTHERMOSTATS OPTIONAL
e boiler is prepared for the application of room chrono-thermo-
stats or remote controls, which are available as optional kits
(Fig. 9).
All Immergas chrono-thermostats are connected with 2 wires
only.
Carefully read the user and assembly instructions contained in
the accessory kit.
Disconnect power to the unit before ma-
king any electrical connections.

On/O Immergas digital chrono-thermostat.
e chrono-thermostat allows:
- set two room temperature value: one for day (comfort tempera-
ture) and one for night (reduced temperature);
- set a weekly programme with four daily switch on and switch o
times;
- selecting the required function mode from the various possible
alternatives:
• manual mode (with adjustable temperature);
• automatic mode (with set programme);
• forced automatic operation (momentarily changing the tem-
perature of the automatic program).
e chrono-thermostat is powered by two 1.5V LR 6 type alkaline
batteries.
“Comando Amico Remoto” (Remote Control Device) V2
(CARV2) with climate chrono-thermostat function.
In addition to the functions described in the previous point, the
CARV2 panel enables the user to control all the important infor-
mation regarding operation of the appliance and the heating sy-
stem with the opportunity to easily intervene on the previously set
parameters, without having to go to where the appliance is instal-
led.
e panel is provided with self-diagnosis to display any boiler
functioning anomalies.
e climate chrono-thermostat incorporated into the remote pa-
nel enables the system ow temperature to be adjusted to the
actual needs of the room being heated, in order to obtain the desi-
red room temperature with extreme precision and therefore with
evident saving in running costs.
e CARV2 is fed directly by the boiler by means of the same 2 wi-
res used for the transmission of data between the boiler and devi-
ce.
“Comando Amico Remoto” (Remote Control Device) V2 or
On/O chrono-thermostat electrical connection (Optional).
e operations described below must be
performed aer having removed the vol-
tage from the appliance.
Any thermostat or On/O environment chrono-thermostat must
be connected to clamps 40 and 41 eliminating jumper X40.
Make sure that the On/O thermostat contact is of the “clean”
type, i.e. independent of the mains voltage, otherwise the P.C.B.
would be damaged.
Any Comando Amico Remoto remote control V2 must be con-
nected to terminals 40 and 41, eliminating jumper X40 on the
P.C.B. ( Parag. 3.5).
e boiler can only be connected to one remote control.
If the Comando Amico Remoto remote control V2 or
any other On/O chrono-thermostat is used arrange
two separate lines in compliance with current regula-
tions regarding electrical systems.
Ensure elimination of this risk before making the boiler
electrical connections.
